DALLAS-The real estate solutions group will occupy the 10th and 11th floors in the Twin Towers complex under terms of a lease valued at $5.7 million. The keys turn Jan. 1 to 36,534 sf leased in "as-is" condition at a building abutting its regional hub.

QUINCY, MA-Margulies & Associates Inc. will design 320,000 sf of office space at One Enterprise Dr. for Blue Cross Blue Shield of Massachusetts, which purchased the building in August for $39.3 million.

ST. PAUL-Negotiations fell through to buy the adjacent parking lot from Meritex Enterprises. The city is now looking at a piece of land north of the renovated headquarters, which would require the demolition of a building.
